I'm trying to get a sample project working for the University C++ courses I teach. I've used SFML in my courses before. It's just supposed to open a window with white background, and then draw a blue circle in the middle. I have it working fine on Windows with MinGW64 and CLion using binaries downloaded from sfml-dev.org. I have it working on MacOS with CLion using command line cmake. I can't get it to work on Windows with Visual Studio 17, I only get a black window. I'm using the same cpp file. I've tried binaries with static and non-static linking. I've built the libraries using cmake-gui and VS 17 and tried static linking. Same results. Any ideas?
Here's my code:
#include <SFML/Graphics.hpp>
// Global Defines
// --------------------------------------------------------
const int WINDOW_WIDTH = 640;
const int WINDOW_HEIGHT = 480;
const sf::Color WINDOW_COLOR = sf::Color::White;
const sf::Color BALL_COLOR = sf::Color::Blue;
int main() {
// create a 2d graphics window
sf::RenderWindow window(sf::VideoMode(WINDOW_WIDTH, WINDOW_HEIGHT), "Hello SFML");
window.clear(WINDOW_COLOR);
sf::CircleShape ball;
ball.setRadius(20);
ball.setOrigin(10.0, 10.0);
ball.setPosition(WINDOW_WIDTH / 2.0, WINDOW_HEIGHT / 2.0);
ball.setFillColor(BALL_COLOR);
while (window.isOpen())
{
// Process user input
// ------------------------------------------------
sf::Event event;
while (window.pollEvent(event))
{
// "close requested" event: we close the window
if (event.type == sf::Event::Closed)
window.close();
}
// Render drawing objects
// ------------------------------------------------
window.clear(WINDOW_COLOR);
window.draw(ball);
window.display();
}
return 0;
}
